' ing extensions of said chamber, and tubular sections connecting said 4extensions.

Another object 1s to provide such a radiator in which said tubular sections progressively decrease in cross-section rearwardly, and of such shape in cross-section as to radiate all heat laterally from their common plane.

A further object is to provide a radiator unit, comprising a vertically extending front chamber having a substantially flat outery face and rearwardly converging sides, oppositely directed lateral openings adjacent t0 said face for nipple connections, rearwardly projecting tapering extensions of said chamber, and vertically extending tubular sections connecting said extensions and progressively decreasing in their cross-sections from said chamber rearwardly., j

A still further object is toprovide a radiator formed of end and intermediate sections having front surfaces, lying substantially in a plane, and adapted to be united by means of nipple connections adj acentto their said front surfaces, the forward portions of the end sections projecting laterally and provided with openings in the rear walls of said projections for valve connections, and said projections being adapted to shelter and substantially hide from view valves connected directly thereto.

And still another object is to provide a perforated grid for such radiators, and olfsets upon adjacent walls of neighboring radiator sections, together with resilient means carried by said` grid and operative to yieldingly lock said grid to said sections by interengagement of said means with said offsets.

Numerous other objects and advantages of the device, aswell as various novel details in the construction thereof, are fully brought out in the following specification, when read in conjunction with the accompanying drawings, in which Figure 1 is a front elevation of one ofthe preferred embodiments of the mvention; Fig. 2 is a rear elevation of the same; Fig. 3 is an enlarged top plan view of ,the same showing the improved gratings or grids in operative position; Fig. 4 is a detailed sectional view of a portion of the radiator shown in Fig. 3 and illustrating the method of securing said grids in position; F 1g. 5 1s a vertical transverse section of one unitary radiator member taken on the line 5--5 of Fig. 3; Fig. 6 is a similar section of the radiator taken on the line 6-6 of Fig. 3

Fig. 7 is ahorizontal section taken on the line 7-7 of Fig. 6; and Fig. 8 is a similar sectionA of one type of radiator end unit;

Referring to thedrawings, the preferred embodiment of this invention is shown as comprising a radiator which may be of a height similar, or equal, to that of the surbase, wainscoting, or other part of the architectural` finish of the interior of a room, said radiator as a unit being made up of a plural-- ity of end and intermediate sections, which may be of any number and height for the purpose of providingfsubstantially any desired amount of heat-radiating surfaces.

The end sections l and 2 are provided respectively with inlet and outlet ports' for the heating fluid employed, the flow of the latter being regulated by means of valves 3 and 4C attached to said ports at the lower and uppermost portions of said end sections. ln fact, each of said end sections is provided with two such ports, but when one of those in a given section is employed, the other may be closed by mea-ns of a suitable plug 5 or by the other valve. These sections comprise a longitudinally extending` fluid channel 6, having a front wall surface 7, terminating in one direction in an outer wall surface 8, disposed perpendicular to the said first surface and both of said surfaces being adapted to embody vany desiredexternal appearance for the purpose of making the radiator consistent in appearance with other architectural features of a given chamber or room of the upper lower and intermediate portions of the said section, thus forming fluid spaces 10,11 and 12, connected to one another by means of tubular channels 13, which latter, theyk progress rearwardly of said radiator sections, preferably decrease infcross-section and are respectively of such shape to direct all radiant heat therefrom laterallyA from their common plane.

Between the two end sections, as shown in Figs. 1 to 3 inclusive, there may be positioned any desired number of intermediate sections which have frontal surfaces 14 which may be provided with any desired configurations to correspond with the external appearance of the surfaces 7 of the said end sections. To the rear of said frontal surfaces, each of said intermediate sections comprises vertically extending fluid channels having a substantially bell-shaped fluid channel 15, the upper and lower of said sections being connected together and to the said end sections by means of any suitable form of inclosed nipples 16 and hexnipples 16.

Each of the rearwardly extending portions of said radiator sections'is rovided with vertically extending` integra 'projections 17, adapted to cooperate directly with the interior wall surface vof a chamber or room in which the radiator is located, whether said projections are of the same extent vertically as the radiator units or not. Furthermore, each of the end and intermediate sections is provided at its up- Vpermostiportion with a flat-topped ridge 18, between which are located independently positioned grids 19, comprising longitudinal .plates 20, connected by transversely extending integral bars 21, between which are formed apertures to permit the air heated by said radiator units to pass upwardly through said grids. Each grid lis provided with a plurality of integral downwardly extending resilient fingers 22, adapted to yieldingly engage the sides of recessed or integrally projecting offsets 23 from the adjacent surfaces of neighboring radiator sections.

It is to be noted that in this type of radiator, the heating fluid flows through the inlet valve 4, or inletv, and into the adjacent end section, whence it flows through the longitudinal channels formed by the upper and lower portions of the wedge-shaped sections and the nipples 16 toward the other end section of the radiator, and thence out by means of the exit valve 3, while a portion of said heating fluid flows from said longitudinal channel through the various rearwardly taperingv channels, connected together as before described, and out and through said last-named valve.

An assembled radiator thus comprises a plurality of longitudinally extending fluid channels andtransversely upwardly extendaprominent as those with the surface of a room or chamber, or

with a lining thereof, in order to form upwardly extending air-flues bounded by said wall surface, said rearwardly and upwardly extending fluid channels .and the frontal portion of said radiator units.

Vith such a construction, it is obvious that the radiant heat from'a great portion of the exterior surface of said radiator units `impinges directly `upon the said chamber wall, thus raising the temperature of the latter and thereby the currents of air which pass immediately ad jacentto it, in addition to heating said air-currents by means of convection from the heated radiator surfaces. Such a radiator as that described may be supported by any desired number of removable` feet 24, which are preferablyin alinement with the rearwardly extending portions of the radiator units and form therewith extensions of the latter as between neighboring Aair-fines, while the entire space below the radiator asa whole may be partially inclosed by any suitable form of artistic paneling'such, for instance, as thesolid panels and grids 25 and 26, shown in Figs. 1 and 2 as being respectively beneath the end and intermediate sections of the radiator.

With the type of radiator just described,

.it is also obvious that there is an added feature residing in the fact that the inlet and 'outlet ports from the end sections lare directed rearwardly so -that the valves secured therein are totally hidden to the rear of the fluid channels 6. On the other hand, if

of the intermediate section illustrated byV Fig. 7. However, one side 28 of this element, instead of being provided only with spaced bosses, as also shown in Fig. 7, for the provision of nipple-engaging threaded portions 29, said side is provided. with threaded openings 30 for the reception of suitable inlet and outlet valves, but the remaining portions of this side are equally as parts immediately adjaa cent to said openings, and as a result may be provided with any desired ornamental configuration. l

Herein there has been thus described a radiator formed of end and intermediate v sections, the latter being cast independently of each other and of said end sections, so that each intermediate section comprises a. vertically extending front chamber, having wardly converging sides, oppositely directed 'lateral openings adjacent to said face for .nipple connections, rearwardly projecting tapering extensions of said chamber, and vertically extending tubular sections connecting said extensions and progressively decreasing in their cross-section from said chamber rearwardly.
